Nearly every kid is fascinated with these rolling red, siren-wailing mystery machines! This romper features a zipper, a snap button cover to keep the zipper pull down and in place and an inseam gusset for a comfy fit. All our products are made with buttery-soft GOTS Certified Organic Cotton and low-impact dyes that are fiber-reactive, meaning the ink becomes one with the fibers, rather than sitting on the surface. The result? Vibrant, colorfast prints that resist fading wash after wash.
